In many Seoul-inspired editorials, the brow is where a soft look gets its structure. A straight, gently filled shape with little arch keeps the face looking open and youthful, and it pairs easily with understated eye makeup.
The technique is light-handed. Start with a shade close to your natural brow color, usually a soft brown or taupe, and use short hair-like strokes rather than a solid line. Keep the front of the brow soft and diffuse, then add definition through the middle and tail, brushing hairs upward with a spoolie to blend.
With brows doing the quiet work, the eyes can stay minimal. A wash of neutral or champagne shimmer, a thin line of brown along the upper lashes and a curled lash are often enough. Lips and cheeks then pick up a small hint of color, keeping the overall look balanced.
Straight brows are one of many ways to frame the face, and the best shape is the one that suits your own features and comfort. This is an editorial category for sorting looks, not a description of how people in South Korea look or what they all prefer.
